Police originally denied the request, but later said that was a mistake.

The department said the video showed an unruly protester being escorted out of the event at Roosevelt Park.

While that was true, the video seemed to focus on Ken Ellis for about 20 seconds. Ellis is an outspoken critic of the Albuquerque Police Department. His son was shot and killed by an APD officer in 2010.

An APD spokesperson told our media partners at the Albuquerque Journal that the officer filmed Ellis by accident.

APD said the undercover officers were not there to do any kind of surveillance.
